High quality resin means plastic, which means scratches. You get what you
pay for.
The ND filters I have are made of glass - no scratches, but they also cost
alot more than $7.00.
If you're real careful in how you handle these, scratch concerns are
minimized.
Mine are rectangular and are used with a Cokin square filter holder so I
don't need a new filter for each different filter size lens - just adapters
sized to the filter holder & the individual lens.
Mine also are graduated neutral density (half clear & half of a neutral
density) that gives me the ability to shift the demarcation line to suit the
scene ie. clear for that area that I don't want to effect the exposure &
half with the neutral density for that area of the scene that I want to
change exposure.
